Test tube bracket for chemical detection experiment based on gear and rack engaging vibration

Abstract

The invention provides a test tube bracket for a chemical detection experiment based on gear and rack engaging vibration. The test tube bracket comprises a mounting base, wherein hoisting devices arefixedly arranged at the right side of the mounting base; the top ends of the two hoisting devices are commonly and fixedly connected with a mounting plate; a plurality of test tube through holes are formed in the mounting plate; rubber sleeves are arranged on side walls of the test tube through holes; the diameter of the rubber sleeves is less than that of test tubes; a plurality of test tube protection devices are fixedly arranged on the mounting base; each test tube protection device comprises a base and a second groove is formed in each base; a first vibration absorption rubber gasket is arranged at the bottom in each second groove; two cavities are formed in each first vibration absorption rubber gasket. The test tube bracket provided by the invention has the beneficial effects that the hoisting devices are used for driving the hoisting of the mounting plate so that the hoisting of the test tubes can be driven; compared with a traditional way of solving the height problem of instruments and the test tubes by utilizing a base plate, the test tube bracket is more convenient and effective; the test tube protection devices can be used for effectively protecting the bottoms of the test tubes and the test tubes are not damaged.

Description

technical field [0001] The invention relates to the technical field of chemical detection experiments, in particular to a test tube support for chemical detection experiments based on rack and pinion meshing vibration. Background technique [0002] Chemistry is a kind of natural science, which studies the composition, properties, structure and changes of substances at the molecular and atomic levels; it is the science of creating new substances. The world is composed of matter, and chemistry is one of the main methods and means used by human beings to understand and transform the material world. It is a subject with a long history and full of vitality, and its achievements are an important symbol of social civilization. There are two forms of chemical change and physical change in chemistry. [0003] Chemical testing refers to the use of chemical analysis instruments, physical and chemical instruments and other equipment to test the finished products of chemical products su...

Problems solved by technology

[0004] In the process of chemical experiments, test tubes are often used. Since the test tubes are easily damaged, they need to be very careful when using them; in some experiments, it is also necessary to shake the test tubes, and the experimenter needs to shake them by himself. Test tubes, when there are many test tubes, the workload is greater
